My VIP722 no longer starts. Just a green light on then off again. Not sure if the internal HD is locked to the receiver itself. If I plug the Internal HD to another DVR say vip622 or 722k, will I be able to transfer the programs off the broken unit to my ext HD then back to a new DVR? I have long cables for the SATA & power without the need to remove the HD. I just want to retrieve the recorded programs and back them up to ext HD pending that the drive itself has not gone bad.
